【摘要】：为量化高速公路路侧景观色彩与驾驶员脑电δ波成分之间的关系,在吉珲高速公路进行道路试验,采集所需数据.首先基于幂函数建立景观色彩值与脑电δ波成分的关系模型,然后考虑驾驶时间对驾驶员脑电δ波的累积影响,基于高斯函数建立驾驶时间与脑电δ波成分的关系模型.最后采用联合建模的方式建立驾驶时间、景观色彩值对脑电δ波成分的影响关系模型.模型分析结果表明:路侧景观色彩均值与驾驶员脑电δ波成分呈负相关,而δ波多在驾驶疲劳时出现,即景观色彩越鲜亮,越能有效避免驾驶疲劳的加剧;驾驶员脑电的δ波成分随着驾驶时间t呈现波动,但是整体仍处于上升趋势,即驾驶员为规避因疲劳导致的行车危险而强制自己处于警醒状态,其自身会存在疲劳与抗拒疲劳的博弈过程.
[Abstract]:In order to quantify the relationship between the landscape color of highway side and the composition of EEG 未 wave of driver, a road experiment was carried out on Jihui Expressway to collect the required data. Firstly, a model of relationship between landscape color value and 未 wave component of EEG was established based on power function. Then considering the cumulative influence of driving time on driving time, the relationship between driving time and 未 wave composition is established based on Gao Si function. Finally, the driving time is established by joint modeling. The model of the influence of landscape color value on the composition of 未 wave of EEG shows that the mean value of landscape color on the road side is negatively correlated with the composition of 未 wave of driver's EEG, and 未 wave mostly appears when driving is tired, that is, the brighter the landscape color is, the more bright the landscape color is. The more effectively the driver can avoid the aggravation of driving fatigue, the 未 wave components of the driver's EEG fluctuate with driving time t, but the overall trend is still on the rise, that is, the driver is forced to be alert to avoid the driving danger caused by fatigue. There is a game process of fatigue and resistance fatigue.
